AUTOMATIC FEED FOR WOOD-BARKING MACHINES.

SPECIFICATION forming part of Letters Patent No. 528,873, dated November6, 1894.

Application filed August 10,1893. Serial No. 482,797. (No model.)

To all whom it may concern:

Beit known that 1, WILLIAM HADLEY, a citien of the United States,residing at Shelton, 1n the county of Fairfield and State ofConnecticut, have invented certain new and use ful Improvements inAutomatic Feeds for- Wood-Barking Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention has for its object to greatly improve the operation andincrease the capacity of wood-barking machines by providin g anautomatic feed therefor which renders hand labor in turning the log thatis being operated upon wholly unnecessary, so that while the bark isbeing removed from a log, the operator is able toget another log inposition to place upon the table the instant the barking of the firstlog is completed, thereby greatly increasing the production of themachine and lessening the cost of running it.

With these ends in view I have devised the simple and novel feedingdevice which Iwill now describe referring by numbers to the accompanyingdrawings forming part of this specification, in which- Figure 1 is aside elevation of a wood barking machine in operation, showing theapplication thereto, of my novel automatic feed; Fig. 2, an endelevation corresponding therewith; Fig. 3, a plan view of the feedingdevice detached; Fig. 4, a plan view of the table with the operativeparts removed; Fig. 5, a side elevation; Fig. 6, an end elevation of thetable detached and Fig. 7 is a transverse section on the line 0c in Fig.5.

It should be understood that my invention lies in the feeding deviceonly and not in the machine itself, my novel automatic feed beingapplicable to any of the various barking machines in use in which thebark is removed by radial cutters on a rotating disk.

1 denotes the casing of a wood-barking machine which is provided with anopening 2 in one side; 3, the rotating disk and 4 radial cuttersthereon. The rotating disk is carried by a shaft 5 which is driven inany suitable manner as by a belt, not shown, passing over a belt pulley6 shown only in dotted lines in Fig. 1. Upon the front end of shaft 5 isa belt pulley7.

8 is a shaft journale'd in bearings 9 which are either cast integralwith or rigidly secured to the table 10.

11 is a bearing cast integral with or rigidly secured to the table,which supports the front end of shaft 5. Shaft 8 carries aworm 12 and abelt pulley 13.

14 is a belt which passes over belt pulleys 7 and 13 and communicatesmotion to shaft 8 and the worm.

15 is a shaft journaled in boxes 16 on the under side of the table.

17 denotes feed rollers, preferably serrated, carried by shaft 15 whichrotate the log that is being operated upon, and 30 a worm wheel engagingworm 12 by which motion is communicated to the shaft. The table isprovided with openings 31 through which the upper portion of the feedrollers project, the log to be operated upon resting upon the upperportion of the feed rollers and against the face of the rotating diskwhich is presented at opening 2.

18 denotes a stop against which the end of I the log rests and uponwhich the log turns. This stop is preferably a ball which is verticallymovable on a standard 19, said stop resting upon a collar 20 which islocked by a set screw. The standard is provided with a base 21 whichlies in an under-cut groove 22 in the table said groove being providedwith an enlargement 23 which receives the head and allows it to bepassed under the overhanging portion of the groove. This standard may bemoved in or out relatively to the casing, and the stop may be moved upor down upon the standard so as to engage either a large or a small logand provide a center for it to turn upon. By presenting a roundedsurface to the end of the log the friction is reduced to the minimum.The table is secured in place by bolts 24:, see dotted lines Fig. 1,which pass through slots 25 in the back plate 26 of the table. The tableis also strengthened so as to support any amount of weight that can beplaced upon it,

by means-of braces 27 engaging sockets 28 which are bolted to the faceof the casing and sockets 29 at the outer edge of the table.

The operation of my novel machine will be I clearly understood from thedrawings. Shaft 5 which carries the cutting disk, imparts motion to theworm which drives the shaft carrying the feed rollers. The exact speedof the feed rollers relatively to the rotating disk is of course not ofthe essence of my invenr tion. Belt pulleys 7 and 13 are so proportionedrelatively to each other as to give satisfactory results with mediumsized logs. Having once properly timed the machine it will not be foundnecessary to change it in use.

Either large or small sized logs may be operated upon withoutappreciable diiference in the efiectiveness of the machine.

Having thus described my invention, I claimsea e73 WILLIAM HADLEY.
